Atomic Absorption Spectroscopy (AAS) quantitative analysis of QD cadmium in organs. Mice were topically exposed to QDs on 0, 4, or 7 days post 180 mJ/cm2 UVB radiation exposure for 24 h. The concentration of cadmium (ng/g tissue) was then measured in various organs including the (a) gauze (epicutaneous), (b) skin (intracutaneous), (c) draining lymph nodes, (d) liver and (e) intestine. The graphs represent the mean +/- standard error (SEM), N = 4. After Kruskal-Wallis analysis (*p < 0.05), there are no significant differences between any QD treated groups; however, all QD treated skin tissue Cd groups had significantly higher Cd compared to no treatment control (No QD, No UVR)
